To all who/m. t may concern:

Be it known that l, W'ILLIAM C. lRvrN, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Metallic Shipping- Barrels, of which the following is a speciication.

The present invention relates to that type of metallic barrels which are formed in halves and shipped to the consumer thereof in a nested condition, being re-assembled at a later period for the shipment of such commodities as cocoa and other oils, which are usually transported from foreign countries. When barrels of this type are reassembled, great difficulty has been experienced in the formation of a hermetic seal or non-leaky circumferential joint union between the two sections of the barrel, and it is to this feature which the herein invention more par ticularly relates, as well as to general constructive features of the barrel sections themselves.

To comprehend the invention, reference should be had to the accompanying` sheet of drawings, wherein Figure l is a perspective view of the assembled barrel.

Fig. 2 is a vertical sectional view of half of a barrel, illustrating its companion half nested therein for shipment. l

Fig. 3 is a broken detail vertical sectional view taken on the line 3--3, Fig. 4 of the drawings, disclosing the manner of securing a head or end to the chime of a barrel section.

Fig. 4 is a sectional view taken on the line 4.-4, Fig. 3 of the drawings, and viewed in the direction of the arrows.

Fig. 5 is a broken vertical sectional view taken on the line 5-5, Fig. 1 of the draw- 1n s.

ig. 6 is a broken vertical sectional view taken on the line SW6, Fig. 1 of the draw- 1n s.

iig. 7 is abrolen sectional view taken on the line,77, Fig. 1 of the drawings, illustrating the manner of uniting the-barrel sections for the forming of a circumferential hermetic sealed joint union.

Fig. 8 is a broken perspective view of the lower edge portion of the upper section of the barrel.

Fig. ,9 is a broken perspective view of the upper edge portion of the lower section of the barrel.

Fig. 10 is a broken perspective view of the split securing clamp ring or band for uniting circumferentially, the two halves of the barrel.

Fig. 11 is a broken detail view disclosing the tightening ring for drawing the clamp band into position for securely uniting the barrel sections end to end.

Fig. 12 is a broken detail view illustrating a modified form of uniting the ends of the split securing clamp band.

Fig. 13 is a. broken top plan sectional view taken on the line 13-13 Fig 12 of the drawings.

In the drawings, Figs. 1 and 2 thereof, the numerals 1 and 2 are used to designate the top and bottom halves respectively of a metallic barrel. To the upper ortop section or half 1 is permanently secured or attached the head end 3, provided with the usual filling opening 4, and tof the lower half'2 is permanently united the bottom end 5. The chime of each barrel section terminates in an inwardly projected angular shaped circum-y ferential flange 6 forming an annular seat into which is forced for seating a correspondingly shaped circumferential ange 7 projected from the ends or bottoms, there being held within the groove formed by such upset flange, of the ends a reinforcing band or ring 8 for strengthening the ends of the barrel when the sections are assembled.

Each barrel section is formed gradually increasing in diameter from the chime end thereofso that one section will nest within another for the purpose of shipment when the halves are unassembled. The ends or heads are applied to the sections by being forced downwardly from the inside thereof until the circumferential flange 7 is firmly seated within the annular groove or channel formed by the circumferential angular flange 6.

The enlarged end of the barrel section 1 is formed with an offset rim 9, which provides an exterior circumferential shoulder 10, and said rim serves as a tongue extension of the section 1, for interlocking with the section 2 on an assembling of the barrel sections-as hereinafter described.

To the section 1 above the shoulder l0 is riveted or welded a reinforcing locking hoop or band 11, which in depth is sufficient to partly overlie the rim 9 and strengthen the same.

The upper end of the barrel section 2 is reinforced by the hoop orband 12 riveted or welded thereto, the upper inner face portion of said band being offset in order to provide in conjunction with the outer wall of the barrel section an annular groove or channel 13, into which seats the tongue extension 9 of the section 1 on the barrel section being assembled.

Each reinforcing hoop or band 11-12, on its upper edge is downwardly inclined outwardly in order to provide a beveled seat a to receive the inwardly inclined faces of a` channeled split lock or clamp band 14.

To one end of the said split lock or clamp band is permanently'secured, by riveting or welding, a tongue extension 15, which on the split ring being fully closed around the united barrel sections overlaps and is secured to the opposite end of said band by spot welding, Fig. 10 of the drawings. v Y

Another manner et uniting the ends of the split clamp band is by means of a fastening lug 16, Figs. 12 and 13 oi"- the drawings, one end of which is passed through an opening 17 formed adjacent one end of the clamp band, and bent over :for attachment. The opposite end of thelug is slightly inclined, sothat asl the Vsplit ring is' drawn together such end will ride upon the inclined tace of the lugopening 18 in the opposite end of the split ring, and is then bent over to hold the ends of therr split ring fastened together. Preference, however, is given to the former described means ot uniting the ends of the split locking ring, but the manner of uniting ther same is an immaterial feature.

J Within the circumferential groove or channel 13 formed by the odset portion of the hoop or band 12 of the lower half or section 12 of the barrel is iitted a gasketring 19,

Fig. 7 vofthe drawings, which is compressed by the tongue extension 9 of the upper haiic or vsection' 1, on the barrel sections being drawn together in orderl to make al tight joint or hermetic seal union between thev said parts'.

'When it is desired to store liquids or semiliquids within the container Jtor shipment or transportation to distant points, as Jfor instance, :trom the Orient to this country, the barrel is assembled by placing the open end of the: sections 1-2 end to end with the projecting extension or circumferential tongue 9 of the section 1 iitted within the circumferential groove or channel 13 of the lower section or half 2. rllhe channeled split fasteningv clamp -or band 14 is then placed around the looselyunited barrel sections toV cover` theV circumierential seam ljoint, the bevel; -faces o thereof bearing on the inclined faces @for the reinforcing hoops 11 Vand 12 ofthe` sections 1f and 2 'respectively There is then placed over the split ring 14 a tightening split ring 20, one end of which carries a holding yoke 21 and the opposite end an ear 22. rThrough the holding yoke 21 and the ear 22 works a tightening screw bolt 23, which when the securing nut 24 screwed onto the extended threaded end of the bolt 22 draws together1 the ends of. the` tightening ring 20, which in turn compresses the clamp band 14 and draws together the ends thereof. ris the `fastening clamp band 14 is compressed circumferentially by the drawing together 'of the split ring 20, the beveled faces b thereof riding on the inclined faces a oi" the hoops 11 and 12 exert a downward pressure thereon and draws the barrel sections 1 and 2 irmly together endwise, the

tongue 9 or the section 1 compressing theV packing ring 19 to form a hermetically sealed circumferential joint union between the sections. W ith the parts in this position, the tongue extension 15 projecting from one end of the split clamp band 14 will overlie its opposing end, and is spot welded thereto to hold the clamp or band 14 in fastened position.

After the filled barrel or container has been delivered to its properl destination, and Y its contents removed, it is onlyrrequired in order to Vdis-assemble the barrel that the spot welded union between the tongue `15 and the clamp 14 be' destroyed orruptured, when thel said clamp may be readily removed and the barrel sections separated to be nested for re-shipment, it being 'understood that the channeled split clamp band or ring 14 may be reshipped with the nested sections of the container, vor a new one supplied witheach reassemblingot the barrel sections. e

By the described invention, there isV pro* vided for the assembling of metallic barrel sections in such a manner as to provide a hermetically sealed circumferential joint union between the barrel sections, thereby providing against the contents ot the barrel or container leaking out at. such joint of union. By the described means, the barrel sections may be quickly assembled when required for use and equally so dis-assembled for purposes or shipmentin a knocked down nested condition.

Having thus described my invention what claim as new and desire to secure by Letters Patent of the United States is 1 A metallic barrel for the shipment of oils or similar commodities, the same comprising an upper and lower conical section, adapted to be nested for shipment, the upper sectionV Y being offset at its open end to provide an.

outer circumferential shoulder, a reinforcing locking hoop securedto said vsection to overlie. the shoulder thereof, a reinforcing locking hoop secured to the' open end of the lower section and offset on its inner tace to provide with the tace ot said section an annular "Lio groove for the reception of the offset portion of the upper section on an assembling of the barrel sections, a packing ring within said annular groove, the upper face of the reinforcing hoop for upper section of the barrel and the lower face of the reinforcing hoop for the lower section of the barrel being downwardly inclined outwardly, a channeled split lock band adapted to embrace the reinforcing hoops and provided with inclined faces for engagement with the inclines of said hoops to draw together the barrel sections on circumferential pressure being applied to said lock band, andr means for uniting the ends of the lock band on the barrel sections being assembled.

In testimony whereof I have signed my name to this specification.
